Maya River Water Conservancy Project

Shangzhi city is located in the mountainous and hilly area, and the Maya River passes through it. Affected by the rainstorm center in the east, it is prone to floods. As early as 1930 (Republic of China 19), the Weihe county government wrote to the provincial government for approval to build a stone retaining dam in the northeast corner of the city, with a length of 50 meters, a height of 4 meters, and an underground repair of 10 meters and a thickness of 0.8 meters. After the founding of New China, the people of this county built dams and dikes themselves. Maya River embankment is a civil embankment. According to the overall planning and design, the total design length in shangzhi city is 134km, and the required earthwork is 2.86 million cubic meters. Existing dikes 1 10 km, of which 38.3 km meet the design standard of once every 20 years.

Maya River Embankment Anti-counterfeiting for 5 years (1938). From May to June, the embankment in the south of Yanshou County was built, starting from the head of He Shan Irrigation District in the west and ending at Maya River Bridge in the east, with a length of about 3.3 kilometers and 63,000 cubic meters of earthwork. From 1958 to 1965, the dike was repaired for six consecutive years. The total project volume reached 350,000 cubic meters, and the dike was extended to 43.6 kilometers. The restoration of the dike in the south of the city has protected Yanshou County and its surrounding cultivated land from flooding. Democratic Village and Minfeng Village in Jiaxin Town, Yanshou County are located on the right bank of Maya River, which are low-lying and often hit by floods. 1967 construction of 2.9 km long democratic dike. Since then, Nongxing Dike, Wanbao Dike, Donghua Dike and Dong 'an Dike have been built on both sides of Mayan River. Liangzhu River Embankment 1974, Liangzhu River Embankment completed. The dike extends from the left bank of Liangzhu River where Jiaxin Commune is located in Yanshou County to Limin Tun, with a total length of 6 kilometers and a total earthwork volume of 75,000 cubic meters. It is connected with Laodaogou in the original Jiaxin irrigation area, forming a dike with a length of about 10 km from Fuan Tun in the south to Limin Tun in the north. It can control the once-in-20-year flood and protect 50,000 mu of cultivated land. 1985, the 1 dike was built on Shili River in Gao Tai Township, Yanshou County, with a distance of 1 km, but there was no dike project in other tributaries of Maya River.

In shangzhi city, there are fish ponds, Yabuli, Mayan and Hedong irrigation areas along Mayan River. As early as 19 18 (7 years of the Republic of China), the Japanese used pond water to irrigate and grow rice on a slope. 1926 (Republic of China 15), there were a few Korean refugees in Hedong area. They used the water source of Maya River to grow rice by a simple method of building dams and opening canals. From 1933 (2 years of pseudo-Datong) to 1940 (7 years of pseudo-Kant), the Japanese pioneering group recruited thousands of Korean farmers as tenant farmers, successively in Sanyu Village, Sanlian Village, Yuchi, Maoershan, Shuinan Village in the west of Yabuli, Shuinan Village in Qingyang, Xinsheng Village, Qingyun Village and Sanyang Village in Weihe River. At that time, the projects were simple, mostly wicker dams and wooden gates, which were only short-term measures and could not resist the impact of floods. At that time, the self-flow irrigation area of paddy fields in the county was 40 thousand mu. In the early days of liberation, some Korean farmers who settled abroad successively built three irrigation areas in Yabuli and Lianghe: Shangli, Guoguang and Jiuli. After the founding of New China, the county's water conservancy construction has developed rapidly. From 1950 to 1955, Liangheping Street Irrigation Area, Qingfeng Irrigation Area and Weihe Xinmin Irrigation Area were built, and four water conservancy facilities such as Yuchi Irrigation Area and Shuinan Irrigation Area were expanded and rebuilt. The self-flow irrigation area of paddy fields in the county has been expanded to 70,000 mu. During the period from 1956 to 1957, all localities followed the water conservancy policy of civilian-run assistance and set off a climax of construction. Maya Irrigation District, Yuanbao Iron and Steel Irrigation District and Qingyang Qinglong Irrigation District started construction one after another. At the same time, five old irrigation areas, such as Hedong, Sanlian and Yangjiadian, were expanded and reconstructed. 1957 gravity irrigation area of paddy field is near120,000 mu. 1958 In the post-People's Commune period, the supporting engineering construction, permanent expansion and transformation of all irrigation areas in the county will be concentrated in batches. By 1978, the gravity irrigation area of paddy field is about130,000 mu. After 1979, the county focused on the thorough rectification or expansion of Hedong Irrigation District, Yan Ma Irrigation District, Yabuli Irrigation District and Yuchi Irrigation District, which have long running time, unstable overall structure, poor comprehensive function or great irrigation potential. Hedong Irrigation District, the largest of which, completed a complete set of water supply projects including Dongan Reservoir, Panshan Canal and Hydraulic Pump Station in 1984. The newly-built Dong 'an Reservoir has an effective storage capacity of/kloc-0.4 million cubic meters and a catchment area of 33 square kilometers. With the completion of the water replenishment project, the actual irrigation area of Hedong irrigation area has increased to 36,000 mu. 1985, there are 4 gravity irrigation areas above 10,000 mu, 15 gravity irrigation areas above 10,000 mu and below 10,000 mu, 104 gravity irrigation areas 1000 mu, and the actual irrigation area is about160,000 mu. From the founding of New China to 1985, the state and collectives have invested10 million yuan for gravity irrigation projects of more than 10,000 mu.
